gasket for ported 4.0 heads

Hi everyone,

I have a dilemma on finding the right manifold exhaust gasket to use for port matching the exhaust & head ports.
Is there a high performance gasket out there for ported heads?

go to jeepstrokers.com . before you port match . very good how-to on this . opening up intakes and how much and where to avoid due to water jackets etc. also do not open up the exhaust too much if any . more of a polish over there . check it out . under faq's i think .

if you open up the exhaust to the gasket you will lose scavenging and velocity .
